AUTOMATIC HYDRAULIC PUMP.

Application filed August 29, 1924. Serial No. 734,934.

The principal object" of this invention is to provide a means for elevating water from a low level which will operate automatically under the constant flow of a low head of Water as found in the ordinary creek or river, thereby providing means for proper sanitation of dwellings, fire protection and general water supply or for irrigation or power.

The principal feature of the invention consists in utilizing a volume of water at a low head to elevate floats which operates a pump to raise a smaller volume of water to a higher level, the water for raising the float being automatically discharged upon the upward limit of the movement of said float.

In the drawings, Figure 1 is an elevational view of my improved apparatus showing a portion thereof in section as indicated by the line 11 of Figure 2.

Figure 2 is a plan view of the apparatus on a slightly smaller scale than Figure 1.

Figure 8 is an end elevational view of the device as shown in Figure 2, a portion thereof being in section as indicated by the section line 33 of Figure 2.

In carrying this invention into eflect a suitable dam 1 is provided in the path of a creek or river where there is a continuous flow of water and a small head of water about five or six feet is produced.

A flume 2 leads from above the dam to a pair of stand pipes 3 whose discharge ends 41 are arranged below the level of the top of the dam and are preferably turned inward.

Between the stand pipes 3 and below the dam are arranged a pair of tanks 5 here shown supported by a concrete reinforcing wall 6. These tanks are arranged equally either side of the pair of stand pipes and suspended upon pivotal bearings are a pair of tilting members 7 for directing the water from the stand pipe discharge ends into one or other of the tanks.

Within the tanks 5 are arrangedthe floats 8 which are of any suitable construction and which have a very considerable buoyancy. These floats are adapted to rise through the hydraulic pressure of water therebeneath flowing through the stand pipe and at either end of the floats are arranged the plunger pumps 9. The pistons 10 of the pumps 9 are connected to suitable brackets 11 carried by the floats 8 so that as the floats are lifted by the pressure of water flowing from above the dam the pump pistons are raised and the water within the pump cylinders is forced upwardly through the valves 12 to the pipes 13 which conduct the water thus pumped to any desirable elevation which will preferably be a supply tank.

rrrranged at either side of. the tanks 5 are cylindrical members 14 each having a valve chamber 15 at the lower end divided from the upper portion by the partition 16 and communicating through the opening 17 with the bottom of the tank.

A discharge opening 18 is arranged in the bottom of each of the valve chambers and said opening is closed hya valve 19, the stem of which passes upwardly through the partition 16 and is connected to a float 20 arranged within the upper chamber of the cylindrical member.

A discharge opening 21 is arranged at the bottom end of the chamber containing the float 20 and this is closed by a valve 22 here shown in the form of a bell crank pivotally supported and spring held in the discharge valve 19 the discharge valve will be opened and the water is very quickly discharged from the tank. These discharge valves are preferably arranged at both sides of the tanks but they may be otherwise disposed.

lVhen the two are used the floats are preferably coupled by the cross bars 25.

Crossbars 26 are supported from the floats 8 and extend outwardly past the cylindrical members 1 1 and secured to the ends thereof are rods 27 which extend downwardly to engage the valves 22 so that when the main floats return to their lowermost position following the discharge of the water from the tanks the rods 27 upon the out lets 21 by engaging the valve 22 allowing the water to escape from the cylindrical members 14 and the main valves to return to their closed position.

Bridge arms 28 connect the pivotal members 7 and these arms extend over the cross bars 26 and are engaged thereby upon the lifting of the main floats, consequently as either float rises when it approaches the maximum position it engages the bridge arm of the tilting members and tilts them so that the stream of water from the stand pipes is then directed into the other tank.

The device is extremely simple. It is entirely automatic and when once set up and started will work continuously as long as there is water above the dam,

The device may be designed to suit any requirements according to the volume of water flowing in the creek or river bed and according to the height to which the water supply is to be elevated. Vi a'ter is fed to the pumps from any desirable source and is confined at the desired level in a suitable container.

Such a device may be applied to the production of power by utilizing the head of water produced by the continuously acting floats. It used for this purpose the water passing through the power developing medium will be returned above the dam and will thereby be used a second time.

A devicesuch as described will be 8X tremely useful upon farms where there is running water as the entire water supply maybe furnished without the use of power.

What I claim as my invention is:

1. An automatic hydraulic motor, C0l11- prising a tank, a float in said tank, means for feeding water to the top of the tank. a discharge valve for the tank, float means actuated by overflow from said tank i'or' opening the discharge valve upon the rising of the main float and means for utilizing the buoyant upward movement of said float.

2. An automatic hydraulic motor, comprising a tank,'a float in said tank, means for feeding water to the top of the tank,

a discharge valve for the tank, a float connected to said discharge valve, a separate fixed chamber enclosing said float and having an inlet from the top of the tank, means for returning the discharge valve and its operatin float to their normal position and means for utilizing the buoyant upward movement of said float.

3. An automatic hydraulic motor, comprising a tank, a float in said tank, means for feeding water to the top of the tank, an opening from the bottom of the tank, a valve chamber connected with said opening, an outlet from said valve chamber, a valve closing said outlet, a fixed float chamber arranged above said valve chamber, an overflow opening leading from the top of the tank to the top of the valve float chamher, a float in said float chamber connected with said outlet valve, a discharge opening at the bottom of said valve float chamber, a valve closing said discharge, means connected with the main float for opening said valve and means for utilizing the buoyant upward movement of said float.

l. in an automatic hydraulic motor, a pair 01 tanks arranged in close proximity, a water feed pipe having a discharge arranged between said tanks, a tilting member adapted to receive and direct the flow from said feed pipe to either of said tanks, floats arranged in said tanks, discharge openings at the bottoms of said tanks, discharge valves controlling said openings, float means for operating said discharge valves controlled by overflow from said tanks, means operated by said tank floats for controlling the valve float means, and means operated by the tank floats for tilting said water supply member.
